PPPL researchers have repurposed a 45-year- old set of magnets to test the design of a spectrometer for ITER, the international tokamak under construction in France. The spectrometer will operate in a magnetic field that is 32 times higher than anything the design, which is used worldwide, has experienced before. Researchers have mounted the spectrometer in the bore of the magnets to see if it can survive the higher fields. ⦿

U.S. Department of Energy Secretary Ernest Moniz dedicated the most powerful spherical torus fusion facility in the world on Friday, May 20, 2016. The $94-million upgrade to the National Spherical Torus Experiment (NSTX-U), funded by the DOE Office of Science, is a spherical tokamak fusion device that explores the creation of high-performance plasmas at 100-million degree temperatures many times hotter than the core of the sun.

A promising experiment that encloses hot, magnetically confined plasma in a full wall of liquid lithium is undergoing a $2 million upgrade at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL). Engineers are installing a powerful neutral beam injector in the laboratory’s Lithium Tokamak Experiment (LTX), an innovative device used to test the liquid metal as a first wall that enhances plasma performance.  Read more

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have challenged understanding of a key element in fusion plasmas. At issue has been an accurate prediction of the size of the “bootstrap current” — a self-generating electric current — and an understanding of what carries the current at the edge of plasmas in doughnut-shaped facilities called tokamaks. This bootstrap-generated current combines with the current in the core of the plasma to produce a magnetic field to hold the hot gas together during experiments, and can produce stability at the edge of the plasma.
